BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 368,341, dated August 16, 1 887.

Application filed November 13, 1886. Serial No. 218,785. (No model.)

To all whom it may concern:

Be it known that I, NICHOLAS KIROHNER, a citizen of the United States, and a resident of the city and county of Philadelphia, and State ofPennsylvania,liave invented certain new and useful Improvements in Machines for Making Bricks,of which the followingis aspecification.

The object of my invention is to furnish a machine which will thoroughly miX and temper the clay and form a perfect brick.

In the accompanying drawings,forming part of this specification, and in which similar letters of reference indicate similar parts th roughout the several views, Figure 1 is a central sectional elevation through the hopper of my machine; Fig.2, a side View; Fig.3, a section of Fig. 2 on line 1 2 3 4; Fig. 4, a rear elevation of guide for back end of reciprocating block; Fig.5, aside-elevation ofactuating-bar for reciprocating block; Fig. 6, a plan of plate and part of lever for closing the upper ends of brickinolds; Fig. 7, a top plan of stationary clay grinder and sifter; Fig. 8, a bottom plan ofmoving clay-grinder,and Fig. 9 a side view ofFig.8.

A is the frame of the machine; B, a hopper; (l, a shaft passing up through the center of this hopperandsupportedinsuitablebearings,DD'; E, a crown-wheel fast on shaft 0, and by means of which said shaft is turned, as hereinafter described; F, blades upon shaft 0 for agitating or mixing the clay; G, a screw upon shaft 0 for forcing the clayinto the molds.

The blades F and screw G are well-known devices in this class of machinery, and will need no further description.

The clay to be formed into bricks is placed in thehopperB bybeingthrown or poured through the spokes ofthe crown-wheel E. It firstpasses through the grinder or sifter,which consists of a disk,H, Figs. 1, 8, and 9,which is fast upon and turns with the shaft 0, and whichis furnished with one or more downwardly-projecting ribs, 1, Figs. 8 and 9, and of a stationary plate, J, Figs. 1 and 7, which is securely fastened to the sides of the hopper B, and which is furnished with slots K, which are larger at the bottom than at the top, and through which the clay falls. The disk H, being revolved, grinds the clay between it and the disk J, and forces it through the slots K, from whence it falls and is mixed by the arms F, and is carried down and forced into the channels L L, which lead to the molds L L. The bricks are formed by plungers M M and by a reciprocating block, N.

The block N is operated as follows:

Upon a shaft, 0, is placed a gear-wheel, I, and this shaft and gear-wheel are driven by a suitable pulley on the shaft, which pulley is not shown.

Q is .a gearwheel gearing into wheel P, and which is carried on a shaft, It. Upon the shaft R is a cam, S, in which a pin, T, projecting from block N, works.

U is a bar projecting at right angles to block N, and to which block N is fastened. V is a crank upon shaft It; \V, a plate carried in suitable guides in uprights Y, which are bolted to the frame of the machine; a, a connecting-rod, one end of which is fastened to crank V and the other end to plate \V; I), an inclined slot in plate XV; c, a pin projecting upward from bar U and carrying a roller which enters slot b.

The revolution of wheel Q causes cam S to be revolved,which causes pin T to travel in slot in cam S and to move one end of block N over. Atthe same time the crankW, through rod a, causes plate W to be moved, and the slot 1) in said plate moves the roller on pin 0 and carries the bar U in, an equal motion being thus given to each end of block N. The rear end of block N is guided in a standard, (I, an elevation of which is shown in Fig. 4. Upon the bar U are rollers U U, which travel upon the bed-plate A of the machine in order to reduce friction.

The plungers M M are actuated as follows:

e e are lovers, the lower ends of which are pivoted to the frame, as shown in Figs. 1 and 2. To the upper ends of these levers are pivoted one end of connecting-rods ff, the other ends of which are pivoted to plates 9 g, which travel in suitable guides in the uprights Y Y. Upon the wheels I and Q, and also upon toothless wheels P Q upon the other ends of shafts R and O,are pins ht h 6. During the revolution ofthese wheels thepins hihz" alternately strike the levers e e and cause these levers to be thrown first forward and then backward, caus ing, through the rods f f, the plates 9 g to be moved backward and forward.

In the plates {/gare inclined slots j j, and projecting up from plungers M M are pins 7:70,

which enter these slots. As the plates M M are moved backward and forward, the slots j j, through pins k k, causethe plungers to be moved in and out. Above the plungers M M and block N is 'a' plate 1, Figs. 1 and 6, the function of which is to close the bottom of passages L L while the bricks are being alternately formed by plungers M M. This plate is operated as follows: Upon the shaft 0 is a cam, m, in which one end of a lever,n, works. This lever is pivoted at '0, and its other end is pivoted to the platel at 11. As the cam turns, the plate I is thrown alternately from one side to the other. After the clay is admitted to mold L the plate Z closes the top of this mold,and thenthe plunger M is moved in, compressing the clay. After it has moved a certain distance the block N begins to move with it, and after they have moved a short distance together the block N increases its speed, leaving the brick, which is pushed by plunger M,on the endless belt q, one of the pulleys, r, of which is shown inFi gs. 1 and 2, and is carried 011' by this belt. ments are given by the inclinations of slots 1) and j in plates W and g and by inclination. of cam S.

The operation of the other side of the machine is similar to the above.

These move- Upon the shaft 0 is a sprocket-wheel,s, which by means of a chain, 1., drives a sprocket-wheel, u, which drives a gear-wheel, v, which drives crown-wheel E and shaft 0 and its connected parts.

The pulley r and belt q are driven from shaft 0 by means of a chain-belt, w, and sprocketwheels as and y.

Having thus described my invention, I claim- 1. The combination, with thehopper B, ofthe revolving disk H,with radially-projecting ribs I, and the stationary disk J ,with slots K, said disk H being placed above disk J and operating to grind and force the clay through slots K in disk J, substantially as described.

2. The combination of block N, cam S, shaft R, wheels 1? Q, crank V, rod a, plate W, with slot 1), and bar U with pin c, substantially as and for the purposes set forth.

3. The combination of wheels I Q,with pins h i, lever e, rodf, plateg,with slotj, and plunger M, with pin 70, substantially as set forth.
